Made the drive from Hilo today passing by the southernmost point in the US. Kona is much more touristy and feels like a giant resort. We are going snorkeling with the Manta rays tonight.
I've been trying to let my GPS location tracking update periodically. It automatically posts to a map in real time. Look through the blog archives to find it.
